FLOATING COMPENSATION ACCELEROMETER Russian patent published in 2006 - IPC G01P15/08 

FIELD: measuring engineering.

SUBSTANCE: floating compensation accelerometer comprises housing with the chamber filled with liquid with magnetic susceptibility. The chamber receives the movable system. The accelerometer also has angle pickup, pickup of moment with movable frame, which are connected with the additional magnetic system through the amplifier and moment compensator. The compensator of the moments of the magnetic forcing out of the frame in the liquid is made of compensation member mounted on the unmovable system and is set in the irregular space of the additional magnetic system. The shape of the space is chosen with regard to the values and signs of the magnetic susceptibility of liquid, frame of the moment pickup, and compensation member. The additional magnetic system can be made of two parallel rod magnets magnetized along the axis, and the compensation member is interposed between them. The compensation member can be also made of a step cylinder whose axis is perpendicular to the rod magnets of the additional magnetic system.

EFFECT: enhanced precision.
